A tool for providing a clamping force and a spreading force in the opposite direction of the clamping force. The tool includes a handle assembly having a trigger and a bar supported by the handle assembly. The bar is configured to move relative to the handle assembly when the trigger is actuated, and the bar includes a slot spanning from a first end of the bar to a second end of the bar. An inner rod is received within the slot, and a detent mechanism selectively couples the inner rod to the bar. The inner rod is received within the first end and coupled to the bar to provide the clamping force when the trigger is actuated, and the inner rod is received within the second end and coupled to the bar to provide the spreading force when the trigger is actuated.

Clamping and spreading tool

An energy-efficient and compact battery charger. The battery charger includes, among other things, a charging port, a power supply module, a battery charger control module or controller, a power control safety module, a battery charger switch, and an indicator. The controller, the power control safety module, and the battery charger switch work in conjunction with each other to control the operation of the battery charger. The controller is configured to execute a charging control process which detects the insertion of a battery pack into the charging port, controls the charging of the battery pack, and controls the illumination or display of the indicator. The power control safety module includes a power control safety circuit that is configured to prevent the charging current and/or the charging voltage from damaging the battery charger or battery pack during a malfunction.

Battery charger

An energy-efficient and compact multi-port battery charger. The battery charger includes, among other things, a power supply module, a battery charger control module or controller, a power switching module, one or more power control safety modules, a plurality of battery charger switches, and a plurality of indicators. The controller, the power switching module, the power control safety modules, and the battery charger switches work in conjunction with each other to control the operation of the battery charger. The controller is configured to execute a charging control process which detects the insertion of a battery pack into a charging port, selects a charging port for charging, controls the power output from the power switching module, and controls the illumination or display of the indicators. The power switching module uses control signals from the controller to switch the power received from the power supply module such that a charging current is applied to a single charging port. Each of the power control safety modules includes a power control safety circuit that is configured to prevent the charging current and/or the charging voltage from damaging the battery charger or battery pack during a malfunction.

A battery tester engages a power tool battery and includes a housing having a cavity for receiving a stem of the power tool battery. The battery tester has a plurality of electrically conductive contacts disposed in the cavity and is configured to engage corresponding battery electrodes on the stem. A processor is mounted within the housing and communicates with the battery through the electrically conductive contacts. The processor measures a voltage level of the battery, and a loading circuit electrically loads the battery during measuring. One or more indicators are controlled by the processor. The processor activates the loading circuit for a predetermined period of time to measure a voltage level of the battery while under load, and then activates the indicators to provide a visual indication of remaining battery life. The battery tester is a stand-alone device where housing does not have a motor or a battery charger.
